AB - <p style="text-align: justify;">Penetration of chloride ions into concrete and diffusion of
moisture in concrete are important factors responsible for the corrosion
of steel in concrete. The two diffusion processes are coupled. This
paper deals with the analysis and simulation of coupled chloride
penetration and moisture diffusion in concrete. Of particular interest
is the parallel programming in finite element method for solving the
coupled diffusion problem. Parallel computing technology has been
advantageous for solving computationally intensive problems. It has
become quite mature technology and more affordable for general
application. Our approach to solve the parallel programming problem is
to use available libraries, i.e. Portable, Extensible Toolkit for
Scientific Computation (PETSc) and The Message Passing Interface (MPI)
standard. The formulation of the coupled diffusion problem, the material
models involved in the differential equations, the details of parallel
domain decomposition technique in the finite element algorithm are
presented. The advantages of parallel programming are demonstrated by a
numerical example.</p>
